Excelsior Park - 1900-1949

Excelsior Park is the renowned manufacturer of this stopwatch movement. This Swiss brand was known in the 20th century for its high-quality chronographs and mechanical stopwatches for sport, science, and military use. This specific model features a 60-second scale on the outside and a 30-minute register (the small sub-dial at the top) to measure longer time intervals. Inside such Excelsior Park stopwatches lies usually the well-known and reliable hand-wound calibre (such as the JB1 or 1-66 movement, often with 7 jewels).
